std atomics
Offers Atomic<T> that can be used with primitive and custom types.
However, it only works with types that can actually use atomic operations: a lock-based fallback for other types is not used!
This crate is based on std's atomics and therefore does not contain any unsafe code!
This crate also does not have any dependencies by default.
If you enable the serde feature, then this crate will depend on serde and Serialize / Deserialize will be
implemented for Atomic<T> when appropriate, using sequentially-consistent ordering.
Simple example with primitive types:
```rust use atomig::{Atomic, Ordering};
let x = Atomic::new(27); // Atomic<i32>
x.store(39, Ordering::SeqCst);
```
This works with almost all primitive types, including f32, f64 and char.
You can automatically derive Atom for your own enum or struct types to use them in Atomic<T>.
There are some limitations, however.
```rust // Requires the 'derive' feature: // atomig = { version = "_", features = ["derive"] } use atomig::{Atom, Atomic, Ordering};
enum Animal { Dog, Cat, Fox }
let animal = Atomic::new(Animal::Cat); animal.store(Animal::Fox, Ordering::SeqCst);
struct Port(u16);
let port = Atomic::new(Port(80)); port.store(Port(8080), Ordering::SeqCst); ```
